Cells
These are the basic structural and functional units of life.
What are cells?
A group of similar cells working together to perform a specific function in the body.
What is a tissue?
A collection of tissues joined in a structural unit to serve a common function.
What is an organ?
A group of organs that work together to perform a particular function.
What is an organ system?
This system provides structure to the body and protects vital organs.
What is the skeletal system?
This is the part of the cell that contains genetic material and controls the cell's activities.
What is the nucleus?
This is the part of the cell that contains genetic material and controls the cell's activities.
What is the nucleus?
This organ pumps blood throughout the human body.
What is the heart?
This system includes the heart and blood vessels and is responsible for circulating blood.
What is the circulatory system?
This organ is the body's largest and is part of the integumentary system, protecting internal organs.
What is the skin?
These specialized structures within a cell perform specific functions, like mitochondria and ribosomes.
What are organelles?
These specialized structures within a cell perform specific functions, like mitochondria and ribosomes.
What are organelles?
Responsible for filtering waste from the blood, these organs maintain electrolyte balance.
What are the kidneys?
This system defends the body against infections and diseases.
What is the immune system?
In addition to bones and muscles, this system includes tendons and ligaments.
What is the musculoskeletal system?
This is the semi-permeable membrane surrounding the cell.
What is the cell membrane?
This is the semi-permeable membrane surrounding the cell.
What is the cell membrane?
This organ is part of the digestive system and is responsible for nutrient absorption.
What is the small intestine?
This system controls voluntary and involuntary actions and sends signals throughout the body.
What is the nervous system?
The leading organ system involved in the exchange of oxygen and carbon dioxide with the environment.
What is the respiratory system?
These structures within a cell are responsible for producing energy through respiration.
What are mitochondria?
These structures within a cell are responsible for producing energy through respiration.
What are mitochondria?
This organ is in the endocrine system and regulates metabolism through hormone production.
What is the thyroid?
This system removes waste from the body and regulates water and salt balance.
What is the excretory system?
These two systems work closely together to deliver nutrients and oxygen to cells, while removing waste products.
What are the circulatory and respiratory systems?
